QNetworkConnectionEvents: fix potential nullptr access
Fix potential nullptr access in QNetworkConnectionEvents::getNetworkConnectionFromAdapterGuid(). This can happen if for some reason the NetworkListManager instance failed to be instantiated in QNetworkConnectionEvents constructor. Fixes: QTBUG-117097 Pick-to: 6.6 6.5 Change-Id: If51ea383e22461a6c3124576c4e1be3f30dde1f6 Reviewed-by: Timur Pocheptsov <timur.pocheptsov@qt.io>
